| Outline of Final Research Achievements |
This project aims at the simultaneous attainment of increased capacity and enhanced cyclability of lithium-ion batteries by using the best of the characteristic composite nanoparticles designed by plasma spray PVD. As the major achievements, we have demonstrated significantly high capacity maintained after longer cycles with the active-material-network in the anode by using the best of the characteristic structure of Si:Sn nanoparticle produced by PS-PVD. The higher cycle capacities with SiO nanoparticles is also attained by the effective reduction during PS-PVD of SiO, along with the new finding that the disproportionation reaction can be accelerated in nanosized SiO. Furthermore, we have also achieved Si nanoparticle production as high as 1 kg/hr. The effect of throughput on the co-condensation process in PS-PVD is clarified and the optimal conditions to produce the optimal composite particles at greater throughputs are proposed.
